DAVID BOURQUE, OF AMESBURY, MASSACHUSETTS, ASSIGNOR TO G. IV. J. MURPHY COMPANY, `OF AMESBURY, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

WINDOW CONSTRUCTION.

Application filed May 29,

To all whom t may concern.'

Be it known that I, DAVID BOURQUE, a citizen of the United States, and resident of Amesbury, in the county of Essex and State of Massachusetts, have invented an Improvement in Window Construction, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

rlhis invention relates to window constructions and the purpose is to provide an improved device whereby the adjustment of a window is facilitated.

lllhile my invention is of general application, I' have for purposeso'f illustration here shown it as applied to a window as ordinarily placed in the door of a closed vehicle such as a limousine.

The construction and operation of my device will best be understood by the ol lowing description of the particular embodiment illustrated in the accompanying drawings wherein Figure l is a vertical section of the door frame ot a' motor carl or similar vehicle, viewedlrom the inner side, and showing the window proper and its operating mechanism inv elevation g Fig. 2 is `a section with the operating handle omitted-and mostv of the door iframe broken away, the' remaining parts being shown substantially along the line 2 2 of Fig. l;

Fig. 8 is a section on the line 3-3of Fig.. 1; and

Fig. l is 'a section on the line slr-4 of Fig. 2.

4number of' lights and be mounted in a sash.

I shall hereinuse the word light to distinguish the window proper from the window including the frame in which it is mounted.

When the light `is raised it closes the open- Speccaton of Letters Patent. Patented Sept. 27, 1921.

ing above the sill 7 and when it is lowered it sinks beneath the sill and is housed within the lower part of the door. The light is guided in its movement in suitable guides at the side of the `frame which will be hereinafter more fully described. For the present I shall disregard their structure and will proceed to a description of the manner in which the light is raised and lowered in the embodiment of the invention shown.

Referring to Fig. 1, in the present instance the major portion of the weight of the light is counter-balanced by means of the spring 13 which is attached to lever 15, which lever carries a roller 17 which runs on a strip 18 (Fig. 2) secured to the bottom edge of the light. The lever l5 swings clockwise, tensioning the spring as the light is lowered and the'spring swings it counterclockwise again as the light is raised.

In the example of my invention here illustrated, the window is operated by a lever 19 which moves crosswise of the window and has a handle 21 presented adjacent the sill oit the same. This lever by means of the bell crank 23 is adapted to work the lazy tongs 25 which carry at their upper' end the pin 27 passing loosely through the strip 18, Iteiierring to F ig. 1, it will be understood that it the handle 21 is swung to the left along the window sill, the lazy tongs 25 will be collapsed and the light will be lowered and movement in the opposite direction will eX- tend the tongs and lift the light. Because of the counterbalance provided by the spring 13, but little force is required to operate the lever 19.

In the embodiment of my invention here shown I have provided means whereby the light is lirmly held in its various positions of adjustment, whereas it may be freely moved when itis desired to raise and lower the same. For this purpose the guides in which it slides are adapted to grip the same. Referring particularlyto Fig. 2, I have here shown the guides as including upper and Y lower channels adapted to receive the light in its lowered and raised positions, respectively. I-Ierein the lower guide consists of two angle bars, a relatively fixed angle bar 29 pivoted at 30 adjacent its lower end and a relatively movable angle bar 31 havthe windowto projections 4l .ing a flange overlapping a flange of the bar 29 (see Fig. 4). The overlapping flanges are joined by means of rivets 33 which are re ceived in diagonal slots 35 in the movable bar 31.r There is thus provided an expansiblechannel and if themovable angle bar 3l is longitudinally shifted, its outwardly pro' iecting flange will be brought correspondingly nearer to or farther away from the opposite flange of the bar 29 according to the direction of movement. The upper channel guide comprises a similar relatively fixed angle bar 29a, pivoted at 30 (Fig. l), and theangle bar 3l is continued to provide the other half of the upper channel. However, the overflapping flange of the angle bar 3l iscut away between the bar-s 29 and 29a so that the two end portions of the angle bar-3l 'corresponding to the two ei;- pansible channel guides are connected sole-- ly by a laterally-yieldable strip of metal 37. Normally, the two channels will be alined in the line kbetween the pivot 30 and the corresponding' upper pivot 3G, but the yielding connection between the saine, which in the present instance is provided for by an integral extension of the parts at 37, permits disalinement as shown in an exaggerated manner in Fig- 2. The purpose of this will appear more fully hereinafter.

I preferably provide means whereby the expansible channels are normally collapsed into gripping relation to the edges of the light 11. For this purpose springs 59.I (Figs. 2 and 3), may be'attached at either side of from the in ovable angle bars 3l, these springs being;` attachedl to suitable fixed point-s on the body of the door. By this means each bar 3l is drawn downwardly, and because of the'inclination of the slots 35, asshown in Fig. 2, the outwardly projectingv iianges thereof will be crowded over toward the outwardly projecting flanges of the bars 29 and 29a' and into `dripping relation to the edges of the light ll. The light ll frictionally engaging the inner side of the flanges will futher tend to thrust `the angle bars 3l downwardly and will thus wedge the saine into gripping relation to itself.

By the construction inst described the light is firmly held and cannot rattle or shift its position of itself. l/Vhen it is desired to move the same, the guiding channels are spread by shifting; the angle bar 3l upwardly against the tension of the springs For tllispurpose l have herein provided pair of arms 43 mounted on a rock shaft 45 and engaging projections 47 from the angle bars 3l at opposite sides of the window.7 respectively. Herein (see Fig. 2) a thrust elemenjt49 is adapted to engage one of' the arms 43 and lift the same. and the shaft 45 will thereby be rocled and the opposite arm shown in Fig. 3 -will' also be operated. Preferably, this thrust member is controlled by a suitable linger grip associated with the operating` handle 2l so that the guiding channels may be expanded and theirl grip on the light relaxed by thc action of the fingers of one hand preparatory to movement of that hand to raise or lower the light.` Referring to Fig. 2 and then to Fig. l, the thrust member 49 as herein shown consists of a wire held against lrinking by a casing 5l and this wire is extended to a position adjacent the handle 2l where it is secured to a block 53 which may be depressed by pressure on the plunger 55 which projects in the manner of a button at the top of the handle 2l. A spring 57 normally lifts thc plunger and thus draws on the wire 49 and since it is held to shape by the casing` 5l the projecting` end is withdrawn from the arm 43 (Fig. 2). permitting the springs 39 to draw the angle bar 31 downwardly. When the plunger 55 is depressed` the wire 49 will thrust the arm 43 upwardly and. liftinga bars 3l against the force of springs 39. spread the llangrcs of the channel guides and release the light for movement upwardly or downwardly by means of the lazy tongs actuated by the swinging` lever 19.

l l shall next describe the manner in which the light is held in elevated position and the manner in which it is disengaged preparatory to lowering. To hold the light in its raised position, it is displaced laterally and supported by the sill 7 Referringr to Fig. 2. l have there shown the lower edge of the light inclosed in al metal strip 59 which at the outside is turned over to form a downwardly facingr hook or channel Gl which is adapted to lit over a projecting Vridloge 63 on the Sill 7. It will be apparent from FiQ'. 2 that when the upper and lower channel .vjuides are in alinement, the outer end of the hoolr` will clear the sill 7 and its ridge 63, but if the light is displaced to the left. as is possible because of the yielding` character of the part 37 and the pivoting' of the guides, the channel may be moved over the top of the ridge G3 and lowered to engage the same. The light will then be securely held in the position shown iu F l and the engaging portions will provide a seal preventingN the entrance of water.

Herein l have shown means for automatically moving the light over toward the sill as it is raised by movement of the lever i9. For this purpose an arm 65, which may be somewhat resilient7 is here shown as extendingr from the lower edge of the light. which arm is provided with auoflset portion 67 (Fig. 1) which forms a follower adapted to coperate alternatively with the diagonal cam surfaces 69 and 71 of a diagonally disposed plate supported by a resilient arm 73 from a part of the door.

Either or both ofthe arms and 73 may be more or less resilient.

Let us suppose that the light is in lowered position and that it is'lifted by swingingl the lever 19 in a clockwise direction over toward the position shown in Fig. 1. Viewing F ig. 2, as the lower edge of the light approaches the sill 7 and has left the lower guide, the offset follower 67 will come in contact with the diagonal surface 69 and as the lifting is continued the light will be yieldingly pressed over toward the sill until .the bottom of thev channel 61 clears the top of'ridge 63 when it will snap over the same. This action will be apparent to the operator who can then release handle 21 and the light will drop by gravity into the position shown in Fig. 2. The yielding pressure of theV offset 67 against surface 69 due to the resiliency of one or both of the arms 65 and 73 will, in coperation with the gripping channels, hold the light snug and prevent any rattling.

If it is desired to lo-wer the window, the handle is given a slight movement clockwise to vraise "the light from the position shown inFig. 1, so that the channel 61 clears the'ridge 63. By this movement the follower portion 67 will be brought above the end of surface '69. The tendency of` the yielding connection 37 between vthe two guides is to bring them into alinement and thus `to move the light to the right, viewing Fig. 2, so that the channel will be clear of the ridge. This is permitted because of the release `of `the spring pressure between the parts 67 and 69. vBecause of the resilient nature of one or'both of them the arm 73'may spring to the -left or the arm 65 to theright. In either event the position of the parts is such that if the lever 19 is now moved anti-clockwise to lower the light through the action of the lazy tongs 25, the follower 67 will now come in contact with the "diagonal surface 71 which, reinforcing the action of the part 37, will draw the samev to the right viewing Fig. 2,

kthus making certain that the parts 61 and 63 will not engage but that the light may be lowered past the sill and into the lower channel guide. By this means the edgeof the light is, as it were switched to and from the sill in raising and lowering the same, respectively.

I have described'in detail the particular embodiment ofA my invention shown in the accompanying drawings. Obviously, while the complete combination of elements described is mostV desirable, certain of them mightbe' used independently `of the rest or with similar devices of a like nature. The eXactmechanical embodiments of the pinciples of my invention chosen Vfor purposes of illustration may also be considerably varied without departing from the scope of "claims 1.
